Lesson 1

### Counting and Writing Numerals up 960

Good morning, class! Today, we are going to learn about the identification and ordering of numbers from 941 to 960. Are you all ready? Great!

Let’s start by identifying the numbers from 941 to 960. We’ll go through each number one by one, so please pay close attention.

First, we have 941. This number is made up of three digits: 9, 4, and 1. The digit 9 is in the hundreds place, the digit 4 is in the tens place, and the digit 1 is in the ones place.

Next, we have 942. Can you tell me which digit changes? That’s right, it’s the digit in the ones place. The hundreds place and tens place remain the same.

Moving on, we have 943. Again, only the digit in the ones place changes. Keep this pattern in mind as we continue.

Let’s continue with the rest of the numbers: 944, 945, 946, 947, 948, 949, 950, 951, 952, 953, 954, 955, 956, 957, 958, 959, and finally, 960.

Now that we have identified all the numbers, we can move on to ordering them from smallest to largest. This means arranging the numbers in increasing order.

To start, we compare the hundreds place of each number. In our case, all the numbers have a 9 in the hundreds place, so we move on to the tens place.

Looking at the tens place, we find that all the numbers have a 4 in that position, except for 950 and 951. Among these two, 950 comes before 951 because 950 has a smaller digit in the ones place.

Now, let’s focus on the ones place. We compare the numbers in this position to determine the final order. After comparing, we find that the numbers from 941 to 960 should be arranged in the following order:

941, 942, 943, 944, 945, 946, 947, 948, 949, 950, 951, 952, 953, 954, 955, 956, 957, 958, 959, 960.

Congratulations, everyone! You have successfully identified and ordered the numbers from 941 to 960. Well done!

If you have any questions or need further clarification, please don’t hesitate to ask.

Lesson 2

### Reverse counting and skip counting

Good morning, class! Today, we are going to learn about reverse counting and skip counting in different intervals. We will focus on counting in 3s, 5s, 6s, 7s, 9s, and 10s, starting from the numbers 941 to 960. Are you all ready? Great!

Let’s begin with reverse counting. Reverse counting means counting backward from a given number. In this case, we will start from 960 and count backward to 941. Listen carefully as I demonstrate:

960, 959, 958, 957, 956, 955, 954, 953, 952, 951, 950, 949, 948, 947, 946, 945, 944, 943, 942, 941.

Well done! You have successfully reverse counted from 960 to 941.

Now let’s move on to skip counting. Skip counting is when we count by a certain number, skipping the numbers in between. We will focus on skip counting in intervals of 3s, 5s, 6s, 7s, 9s, and 10s. Pay close attention as I guide you through each interval:

Counting in 3s:

941, 944, 947, 950, 953, 956, 959.

Counting in 5s:

941, 946, 951, 956.

Counting in 6s:

942, 948, 954, 960.

Counting in 7s:

945, 952, 959.

Counting in 9s:

945, 954.

Counting in 10s:

950, 960.

Great job, everyone! You have successfully skip counted in intervals of 3s, 5s, 6s, 7s, 9s, and 10s starting from the numbers 941 to 960.

Remember, practicing reverse counting and skip counting helps us become more familiar with numbers and strengthens our number sense. Keep practicing at home, and you’ll become even better at it.

If you have any questions or need further clarification, please don’t hesitate to ask.

### Introduction of litres as units of measuring liquid

Good morning, class! Today, we are going to learn about measuring liquids using the unit called “litre.” Are you all ready? Great!

Imagine you have a bottle of water or any other liquid in front of you. Have you ever wondered how we can measure the amount of liquid in that bottle? That’s where the unit of measurement called “litre” comes in.

A litre is a unit used to measure the volume or the amount of liquid in a container. It helps us understand how much liquid is inside a bottle, jug, or any other container.

In simple terms, a litre is a way of telling us how much liquid a container can hold. It is represented by the symbol “L” or “l”. When we measure liquids, we often use litres because it is a commonly used unit.

Now, let’s understand how we can visualize a litre. Imagine a milk carton or a juice box. You may have seen those containers in the grocery store. Typically, those cartons or boxes hold one litre of liquid. So, when we say we have one litre of milk or juice, it means we have the same amount of liquid as one of those cartons or boxes can hold.

We can also have larger or smaller quantities of liquid. For example, if we have half of a milk carton or juice box filled with liquid, we would say we have 500 millilitres (ml) or half a litre. Millilitres are smaller units used to measure smaller amounts of liquid.

In summary, a litre is a unit of measurement used to measure the volume or amount of liquid in a container. It helps us understand how much liquid a container can hold. We often use litres to measure larger quantities of liquid, while millilitres are used for smaller amounts.

I hope this explanation helps you understand the concept of a litre as a unit of measuring liquid. If you have any questions or need further clarification, please don’t hesitate to ask.

### Measuring liquid eg graduated measuring cylinder up to any stated number like 200 litres

Good day , class! Today, we are going to learn about measuring liquid using a graduated measuring cylinder. Have you ever seen a measuring cylinder before? It’s a tool that helps us measure the volume or amount of liquid very accurately. Are you all ready? Great!

A graduated measuring cylinder is a tall, cylindrical container that has measurement markings on the side. These markings allow us to measure the volume of liquid in millilitres (ml) or litres (L).

Let’s imagine we have a graduated measuring cylinder that can measure up to 200 litres of liquid. That’s a lot of liquid, isn’t it? The cylinder has markings along its length, and each marking represents a certain volume of liquid.

For example, the first marking might represent 10 litres, the second marking might represent 20 litres, and so on, until we reach the maximum capacity of 200 litres. The markings in between represent smaller increments, such as 5 litres or even 1 litre, depending on the size of the cylinder.

When we want to measure a specific amount of liquid, we carefully pour the liquid into the measuring cylinder until it reaches a certain level. Then, we read the measurement from the markings on the side of the cylinder.

For instance, if we pour liquid up to the marking that represents 50 litres, we can say that we have 50 litres of liquid in the cylinder. If we pour more liquid and it reaches the marking that represents 75 litres, then we have 75 litres of liquid.

It’s important to read the measurement carefully, making sure to align our eyes with the liquid level and the markings on the cylinder. This ensures that our measurement is accurate.

Measuring liquid using a graduated measuring cylinder is an essential skill in various fields, such as science, cooking, and many other areas where precise measurements are needed.
